There's a handful of variables that may impact the price. However, you can expect to pay between $2.50 and $4.00 per installed watt of solar power for a grid-tied system.

Yes. As sunlight is sufficient in our region, installing solar panels is a financially viable option.

Residentially speaking, we see an average ROI of 10-14 years. Commercial projects can have a payback period as low as eight years.

The solar panels we use have a minimum performance warranty of 25 years.

There is a minimum of 30 years from a panel, with an average annual degradation of 0.5% in performance.

On one hand, a microinverter converts DC power from the panel to AC power at the array, typically connecting 1-4 panels to each inverter. On the other, a string inverter connects all panels in 1-3 strings and converts DC power to AC away from the array.

More often than not, panels require minimal maintenance. However, regular checks by your installer or a service provider are ideal.

A federal tax credit is available for solar power. The residential credit is $5695, and the commercial credit is $3468. Commercial systems may also qualify for accelerated depreciation. Please consult www.dsireusa.org for additional incentives.
